Answer:
g = - 5
Step-by-step explanation:
2 - 8g = -3 - 9g
Add 9g to both sides of the equation:
2 - 8g + 9g = -3 - 9g + 9g
2 + 1g = - 3
Subtract 2 from both sides of the equation:
2 - 1g - 2 = - 3 - 2
1g = -5
Divide both sides of the equation by 1:
g = -5
Answer:
C. Events E and A are independent
Step-by-step explanation:
we will verify each options
(a)
We can use independent events formula
P(B∩C)=P(B)*P(C)
we are given
P(B)=0.4
P(C)=0.25
P(B∩C)=0.05
now, we can plug these values into formula
and we get
0.05=0.4*0.25
0.05=0.1
we can see that left side is not equal to right side
so, this is FALSE
(b)
We can use independent events formula
P(D∩A)=P(D)*P(A)
we are given
P(D)=0.25
P(A)=0.6
P(D∩A)=0.1
now, we can plug these values into formula
and we get
0.1=0.25*0.6
0.1=0.15
we can see that left side is not equal to right side
so, this is FALSE
(c)
We can use independent events formula
P(E∩A)=P(E)*P(A)
we are given
P(E)=0.5
P(A)=0.6
P(E∩A)=0.3
now, we can plug these values into formula
and we get
0.3=0.5*0.6
0.3=0.3
we can see that both sides are equal
so, this is TRUE
(d)
We can use independent events formula
P(D∩B)=P(D)*P(B)
we are given
P(D)=0.25
P(B)=0.4
P(D∩A)=0.15
now, we can plug these values into formula
and we get
0.15=0.25*0.4
0.15=0.1
we can see that left side is not equal to right side
so, this is FALSE
0.05 mm * ? days = 0.75 inch
Use proportions
1 mm = 0.0394 inch
0.05 mm = 0.00197 inch
0.75 inch / 0.00197 inch = 380.71
380.71 days / 30 days = 12.7 months
Answer:
8
Step-by-step explanation:
Make x the answer the the equation by swapping the answer with x
6+2=x
Then solve and plug in the variables
8=x
8-6=2
